The cost of a new boiler installation depends on the boiler model, your property type, hot water demand, and whether a power flush or flue relocation is required. Call 07472 251465 for a free, no-obligation quote. Ralf will assess your property and give you a fixed price before any work is booked. Every installation includes removal of the old unit, supply and fitting of an A-rated boiler, full system flush, magnetic filter, smart thermostat, and Gas Safe installation certificate.

Most boiler replacements take one day. Ralf arrives in the morning, removes the old unit, fits the new boiler, connects the smart thermostat, flushes the system, tests all radiators, and hands over the Gas Safe installation certificate — all on the same day.

Power flushing professionally removes sludge, rust, and magnetite from your central heating system. You need one if you have cold spots on radiators, the boiler is making banging or kettling noises, heating is slow, or gas bills have risen. Most boiler manufacturers require a clean system as a warranty condition.
